BUT, you can determine the orientation and keep placing them in that orientation. All you have to do is consistently apply the red “before” image of the placement square in the same place. For instance, if you place a block with the red square against a previously placed block, the orientation will always be the same.
IF you place one against the far wall, it changes. If you place it against the bottom, it changes. IF you keep placing the blocks against the same “edge” as before, they will always line up correctly.
